な湿式ミルスラリ原料の供給方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for supplying raw materials for wet mill slurry, in particular a method for supplying solid particles such as coarsely pulverized coal particles and chemicals such as water and dispersants to a mill. The present invention relates to a wet mill slurry raw material supply method suitable for preventing clogging and adhesion in a supply system for supplying raw materials to a mill when obtaining slurry.

石炭−水スラリのミルへの供給系統を示す。FIG. 4 shows a system for supplying coal-water slurry to a mill as an example of a method for supplying slurry raw materials for the Type 1 mill.

合される。In Fig. 4, coal 1 is coarsely crushed through a crusher 2, and then sent to a hopper 3 and a downspout 4 at the bottom of the crusher.
It is further fed into the mill 14 through a screw feeder 5 provided in the horizontal direction. On the other hand, water 7 and additive 12, which are fluidizing media necessary for slurrying, are introduced into the mill 14 in a mixed state through a nozzle 13a through a buffer tank 10, and are mixed during the process of pulverizing the coal. .

。When the coal is crushed in the mill 14, it is desirable that the coal particle size at the inlet of the mill 14 does not change over time in order to keep the particle size of the slurry that comes out as a product constant, and the crusher 2 keeps the particle size almost constant. That is important.

があった。However, if the coal is coarsely crushed by crusher 2,
Particles as large as 1Q mm or more disappear, resulting in coal particles having a small particle size, and this, together with the influence of moisture contained in the raw coal, makes it easier for the coal particles to adhere. Especially in the figure,
There were problems in which fine powder particles adhered to the inner wall surface of the screw feeder 5 and the screw surface, and coal particles clogged the part where the screw feeder 5 entered from the downspout 4, making it impossible to feed raw coal. Furthermore, a similar problem occurs in a system that supplies coal particles containing moisture obtained by dehydrating a slurry containing coal particles at a low concentration to a mill.
このような現象は、石炭粒子の場合に限らず、他の固体
粒子の場合にも同様に生じることがある。Such a phenomenon may occur not only in the case of coal particles but also in the case of other solid particles.
本発明の目的は、上記した従来技術の問題点を解消し、

とにある。The purpose of the present invention is to solve the problems of the prior art described above,
It is an object of the present invention to provide a method for supplying raw materials for wet mill slurry, which can prevent clogging of solid particles produced in a system for supplying solid particles to a mill and can stably supply solid particles.

。The above purpose is to combine all or part of the fluidizing medium to be introduced into the mill with the solid particles in the supply system that supplies the solid particles to the mill, and to transfer the combined body to the mill through the solid particle raw material supply system. This is achieved by introducing

ともに供給系統内を流動する。When solid particles are transferred, the adhesion frictional resistance of the solid particles to the inner wall surface of the supply system is large, and the solid particles stagnate on the inner wall surface. When a fluidizing medium such as water or a dispersant is mixed in a supply system for solid particles such as coal particles, the fluidizing medium constantly flows even on the inner wall surface, which reduces the resistance that overcomes the adhesion frictional resistance. That is, due to the improved fluidity, the solid particles flow through the supply system together with the fluidizing medium without adhering to the inner wall surface.

Coal l is crushed by a crusher 2 and falls inside a hopper downspout 4 vertically installed. Next, the crushed coal that has entered the horizontally installed screw feeder 5 is fed into the mill 14 by the rotation of the screw. On the other hand, water 7, which is a medium necessary for slurrying, is supplied to the hopper 3 via a flow meter 8b, a valve 9, and a buffer tank 10, and via piping 1). Furthermore, additives 12 such as dispersants, which are important for providing fluidity, are branched into two lines of piping, one enters the buffer tank 10 via a flow meter 8a and is mixed with water 7, and the other additive 12 is directly introduced into the mill 14 from the nozzle 13 via the flow meter 80.

となって流下する。FIG. 2 is a detailed view of section A in FIG. 1. In FIG. 2, water pipes 1) are arranged in a ring shape around a hopper 3 in the coal passage, and a large number of pipes are formed toward the center of the hopper. These many pipes are each connected to a water inlet 15 formed on the inner wall surface of the hopper 3 at a predetermined interval. Therefore, the water 7 as a fluidizing medium from the water pipe 1) flows down from the water inlet 15 onto the inner wall surface of the hopper 3 in the form of a liquid film.
次に第１図および第２図を基に本実施例の作用について
説明する。Next, the operation of this embodiment will be explained based on FIGS. 1 and 2.

の方が大きく停滞し、柊には閉塞を引き起こす恐れがあ
る。The coal l coarsely crushed by the crusher 2 contains more fine particles than before crushing, and the specific surface area (surface area per unit weight) of the entire coal particles increases. For this reason, when particles fall down the hopper 3 and downspout 4 by gravity, or when they move inside the screw feeder 5 by the rotation of the screw, frictional resistance increases when particles come into contact with the inner wall or equipment surface. If the charcoal is damp, it will stick, and the resistance due to friction will outweigh gravity and feeder transport capacity, causing stagnation, which may cause blockages in the holly.

石炭粒子の付着性に応して上記媒体を壁面へ供給するこ
とが必要となる。The important point here is the contact friction resistance between the inner wall surface to which the coal particles are attached and the coal particles, and the balance between the adhesion (resistance to falling off) force and the peeling force is the issue. In other words, in the area where large particles exist on the upstream side of the crusher 2, even if fine particles adhere to the inner wall surface, they will peel off (fall off) due to the inertia of the large particles, so it is necessary to prevent adhesion to the wall surface using a fluidizing medium. I don't. However, in areas where there are no coarse particles, the peeling force due to the movement of particles alone is smaller than the adhesion force, so the adhesion and growth of particles progresses, eventually leading to blockage. For this reason,
It is necessary to supply the medium to the wall depending on the adhesion of the coal particles.

る。In the example shown in FIG. 1, since adhesion of coal particles coarsely crushed by the crusher 2 on the downstream side poses a problem, a fluidizing medium is supplied from the outlet of the crusher 2 onwards. Therefore, the supply of solid particles of the fluidizing medium in the supply system is not limited to the supply system of raw coal, but also the supply system that supplies slurry after dehydration of low-degree pulverized slurry to the mill, and the supply system of coal that does not involve coarse crushing. It is also effective in preventing the adhesion of solid particles in systems containing solid particles.
第２の方法として、壁内面へ流動化媒体を液膜状にして
供給することなく、石炭粒子と流動化媒体とを混合し、
全体に流動化を持たせる方式を採用することもできる。As a second method, the coal particles and the fluidizing medium are mixed without supplying the fluidizing medium in the form of a liquid film to the inner wall surface,
It is also possible to adopt a method that provides fluidity throughout.
この場合も、内壁面での付着摩擦抵抗に打ち勝つ抵抗の
低下（流動性向上）とすることにより安定した運用が可
能となる。また、第１図に示す方式および前記第２図の
方式の場合、内部に機械的な攪拌移送・攪拌手段を補助
的に設けることにより固体粒子の付着防止をより効率的
に行うことができる。In this case as well, stable operation is possible by reducing the resistance (improving fluidity) to overcome the adhesion frictional resistance on the inner wall surface. In addition, in the case of the method shown in FIG. 1 and the method shown in FIG. 2, the adhesion of solid particles can be more efficiently prevented by providing an auxiliary mechanical agitation transfer/stirring means inside.

がある。したがって、実施例では、添加剤をミル内へ直
接入れるノズルを設けているが、添加剤の全量を原炭供
給系統に合流させてもよい。Fluidization (adhesion prevention) is achieved by using one or both of water and additives as a fluidization medium. In this case, by merging the fluidizing medium upstream of the supply system with the raw coal rather than independently supplying it into the mill, the supply section to the mill inlet, which is a rotating body (screw), is reduced to 1. It has the advantage that the mill inlet is cylindrical, reduces the need for mill design, disassembly and inspection, and eliminates problems such as clogging of water and additive nozzle openings in the mill. Therefore, although in the embodiment a nozzle is provided to introduce the additive directly into the mill, the entire amount of the additive may be added to the raw coal supply system.

In this case, water and additives may be used in combination, but from the point of view of obtaining a predetermined slurry without reducing the concentration of the feedstock, only the slurry from the mill 14 is used for the coal particles. Adjust the amount (co-supply or mill 1 for this slurry)
A fluidizing medium may be supplied to the coal particles within a range where the degree of slurry obtained from Step 4 can be adjusted.
第３図は第１図のＡ部の他の例を示す詳細図である。FIG. 3 is a detailed diagram showing another example of section A in FIG. 1.

うになっている。In Fig. 3, a water tank 16 is provided around the hopper 3 in place of the ring-shaped water pipe, and the water pipe 1) is communicated with the water tank 16, and the hopper 3 has a double structure so that water 7 and water are added in an overflow manner. A fluidizing medium for the agent 12 is provided.
この方式では、ホッパ３およびダウンスパウト４の内壁

る。In this method, the medium can be supplied in the form of a uniform liquid film to the inner wall surfaces of the hopper 3 and the downspout 4 in a cross section perpendicular to the axes, so that adhesion to the inner wall surfaces can be more completely prevented.
上記実施例の方式は、石炭−水スラリの場合について示

適用可能である。Although the method of the above embodiment is shown for the case of coal-water slurry, it is equally applicable to solid and liquid supply systems.
